Highway History:1953: OK 51A was less than a mile long and connected OK 51 to Southard.
1959: OK 51A had been extended south to OK 8, but still had its other end at OK
51 west of Southard.

Highway Review:OK 51A is the longest suffixed route in Oklahoma. It is 23 miles long and
connects OK 8 north of Watonga to OK 51 and OK 58. OK 51A has been resurfaced
and straightened out in recent years. During this process, its southern terminus
moved about two miles to the north.
